CO2e - Greenhouse Gas Emissions Approved

Environmental Monitoring & Emissions Monitoring

Across industries, companies are beginning to see more pressure to reduce emissions. Regulations regarding the monitoring or reduction of emissions are growing in intensity. This pressure goes across boundaries: political and industrial.

“Leading governments at every level around the globe have set standards and made investments in promoting GHG reductions in economic jurisdictions large and small.” – Michael Northrup.
The EU has committed to the goal of reducing emissions by 20% by 2020. Even Japan’s green IT project plans to drop 130 million tons of CO2 by 2025. In the U.S., President Obama signed an Executive Order on Federal Sustainability that committed to reduce greenhouse gas emissions by 28% by 2020.

Many industries around the world are affected by these regulations and must respond by improving their processes and technologies, increasing efficiency, and installing monitoring equipment to measure the flow of emissions. International companies, like those operating in the Oil and Gas Industry, are often affected by more than one nation’s regulations regarding the reduction or monitoring of emissions. The International Petroleum Industry Environmental Conservation Association and the American Petroleum Institute have recently joined forces to assist such companies in the process of trying to comply with all of these various regulations by creating a guide to institute reduction projects.

Flare Gas Flow Meters for Direct Mass Measurement in Flare and Combustor Gas Applications

Flare stacks and enclosed combustors (or vapor combustors) are used to burn waste gases from Oil & Gas Production, gas processing facilities, dehydration facilities, tank batteries, tank farms, and industrial plants. These flares often convert chemical and organic hydrocarbons into primarily water vapor and CO2. Some processes also use relief valves to vent flammable gases to the flare stack during upset conditions.

Flare Gas Stacks with Fox Flowmeters
Other applications for flare and combustor gas flow meters include oil and gas well drilling operations, oil refineries, chemical process plants, gas distribution infrastructure, and landfills. Flares and combustors are subject to stringent regulations, requiring operators to measure, record and report the amount of flared gases.

Due to the potential for large changes in flow rates, density, pressure and gas composition, flare gas measurement is one of the most difficult and demanding flow applications. Fox thermal mass flow meters have demonstrated their ability to measure the low flow rates typical of normal flare conditions, and also the high velocities found in upset conditions. A flare gas meter by Fox is especially equipped for flare applications.

Fluid composition and installation anomalies can also affect flare gas flowmeter performance. Fox Thermal Instruments’ Calibration Lab employs a wide range of gases, gas mixtures, temperatures, pressures and line sizes to simulate actual fluid and process conditions while calibrating flare gas flowmeters. This real-world approach improves installed accuracy and minimizes measurement uncertainty.

Advantages of a TFH 3000 Flare Gas Flow Meter in Emissions Monitoring Applications for Flares or Combustors:

  • Exceptional low-flow sensitivity for accurate measurement over a wide range of flaring operations
  • Heated stainless steel sensor is suitable for corrosive, particulate-laden gas streams
  • No temperature and pressure compensation required
  • Direct Mass Measurement
  • Built-in alarms, totalizers and a wide variety of communications protocols available for easy interfacing with emissions management systems

Vent Gas Flow Meters for Direct Mass Measurement in Vent (Flash) Gas Applications

Rising levels of volatile organic compounds (VOCs) in the atmosphere are a subject of general concern and increasing environmental regulation. In order to monitor and quantify emissions, VOC concentrations as well as VOC flow rates must be measured to evaluate mass emission rate. Purchasing flash gas flowmeters or vent gas flowmeters is a common way to measure these emissions.

The major reason for monitoring VOC emissions is to provide information for environmental audits (40 CFR Part 98). However, VOC monitoring with a flash gas flow meter or vent gas flow meter can also help you:

  • Identify opportunities to reduce emissions
  • Evaluate performance of existing abatement equipment
  • Identify and correct sources of fugitive emissions
  • Demonstrate continual improvement in environmental performance
  • Meet health and safety requirements and improve working conditions
  • Optimize process flows throughout the plant or storage facility

The thermal mass flow meter's ability to provide a direct reading of mass flow rate without additional pressure and temperature instrumentation makes it ideal for measuring flow rates in flare stacks, ducts and tank vents. A flash gas flowmeter or vent gas flowmeter from Fox is the ideal way to measure these emissions.

Advantages of TFH 3000 Flash Gas Flow Meters and Vent Gas Flow Meters in emissions monitoring applications:

  • Exceptional low-flow sensitivity provides accurate measurement over a wide range of venting and flaring operations
  • Heated stainless steel sensor is suitable for corrosive, particulate-laden gas streams
  • No temperature and pressure compensation required
  • Direct Mass Measurement
  • Built-in alarms, totalizers and a wide variety of communications protocols available for easy interfacing with emissions management systems
